I'm in the process of migrating my website to another server and I want to test paypal on the new server.
Everything is working correctly, except that the IPN is not being executed on my new server.
What I am doing is changing the notification URL in the IPN preferences page. If I leave the old server's address in the notification URL field, and then buy something on the new server, it runs the script on the old server. When I change the notification URL to the new server, nothing happens. The URL points to the right place and the purchase is recorded in the seller accounts recent activity.
Is there something else I need to change that I might have missed?
Thanks.
